In a Cisco UCS domain, virtual host bus adapters (vHBAs) provide the connection between servers and the fabric interconnects. To create redundancy, it is recommended to create two vHBAs per fabric for each server.

The maximum number of servers that can be utilized in a Cisco UCS domain depends on several factors, including the number of chassis and the number of fabric interconnects. Each fabric interconnect can support up to 8 chassis, and each chassis can support up to 8 servers. Therefore, the maximum number of servers that can be utilized in a Cisco UCS domain is:

Maximum number of servers = Number of chassis x 8

Let's evaluate each option based on this formula:

A. 12 chassis (96 servers) Maximum number of servers = 12 x 8 = 96 servers

B. 20 chassis (160 servers) Maximum number of servers = 20 x 8 = 160 servers

C. 15 chassis (120 servers) Maximum number of servers = 15 x 8 = 120 servers

D. 16 chassis (128 servers) Maximum number of servers = 16 x 8 = 128 servers

Based on the formula, the option that lists the maximum number of servers that can be utilized in this domain is option B, which allows for up to 160 servers (20 chassis x 8 servers per chassis). Therefore, the answer to the question is B.
